Annotation Type TransactionAttribute

The TransactionAttribute annotation specifies whether
the container is to invoke a business method within a transaction
context.
The TransactionAttribute annotation can be used for
session beans and message driven beans. It can only be specified
if container managed transaction demarcation is used.

The annotation can be specified on the bean class and/or it can be
specified on methods of the class that are methods of the business
interface or no-interface view.

Specifying the TransactionAttribute annotation on the
bean class means that it applies to all applicable business
methods of the class. Specifying the annotation on a
method applies it to that method only. If the annotation is applied
at both the class and the method level, the method value overrides
if the two disagree.

The values of the TransactionAttribute annotation are
defined by the enum TransactionAttributeType. If
the TransactionAttribute annotation is not specified, and
the bean uses container managed transaction demarcation, the semantics of
the REQUIRED transaction attribute are assumed.
